I was getting this same issue. It would force close after about 5 min. like clockwork.
1)I went in and deleted the game files/ folder stored on the SD card manually.
2)Then I restarted the game and let it redownload them.
3) I then soft reset the phone ( removed battery with phone still on, then waited 10 sec-- not sure if it's completely necessary) turned phone back on.
I haven't had any issues since. Played the game for about an hour with no problem. I suspect it was a software issue. Also could be Androids OS related. Something like memory/resource management. Nor sure. Also could've been just corrupt game files from my initial download.
Anyhow, hope this helps someone. Helped me.
I'm running 2.3.2.
